APPARATUS FOR GENERATING GAS.

Application filed January 22, 1919. Serial No. 272,46

To(illwhomtnwy come m: battery consists of two main generators 5 Be it known that l, Hour-on lia'rciinmn, a and a central receiver generator 6. The citizen oi the United States residing; at n generators 5 are coni'lected by pipes 7 Boston in the coui'ity of t'lutlolk and State with the receiver generator (5 aml these pipes 60 5 ct Massachusr ts, have invented certain. new are provided with valves 3, the purpose 0t and useful lnmrovements in Apparatus tier which valves is to render it possible to con- Generating Gas oi which. the loilowiilpg is nect the main generators to or disconnect a. specification. these generators from the receiver generator.

This invention relates to an apparatus for Each generator is provided with a stack 9 65 10 generating gas and it has tor its object the having a valve 9 located therein. lneach provision of an. imprm'ed device of this of the main generators a heating element character con ructed in such manner as to indicated as a gas burner l0 is provided cllic'ent-ly gene e a water gas with a miniwhich is supplied with gas through a valreil mum of waste and with the greatest pipe 11 and the purpose oi which burner is 70 economy. JhS the best result in chemical to periodically heat a mass 0t fire-proof inacombinations, is secured when the elements terial 12. This may be ofl't any suitable nato be combined are first linely divided and ture, but I prefer to use lire-prool clay conreduced to as homogeneous a condition as taming about 36% oi sawdust, the saw-dust possible so when it is desired to secure a debeing mixed with the fire-clay and the whole 7 composition or a. dissociation it is equally then baked and the resultant mass broken to as desirable that the material be brought thedesireddegreeot fineness. Nozzles 13 proto the point at which such action is to take ject through the walls of the main generators place, in as homogeneous a condition as and serve thepurpose o't directingupon the possible. To this end I contemplate pro mass 12 a spray or. hot water and finely 80 vidinga highly heated mass and bringing powdered coal dust, the water and coal into contact therewith a spray of heated dust being thoroughly mixed to constitute water and finely divided coal dust in a a homogeneous and uniform mixture which, thoroughly mixed and homogeneous condiwhen it strikes the heated mass 12, is COI1- tion, whereby the utmost efficiency of the apverted into water gas. Sight openings 85 paratus is attained and the results are are provided in the walls of the generator rendered certain and uniform. Furthen and I preferably provide grates 15 and 16 more, since all of the material strikes the to thereby constitute within each of the main heated mass in such condition that the unnerators an upper decomposition chamber heated mass may act most efficiently thereon 17 and a lower decomposition chamber 90 it "follows that a mininuim of residual will At 19 and 20 l. have indicated handles for result and great eiiiciency will be secured. shaking the grates, ii desired, this latter The apparatus shown in the accompanybeing merely for the purpose of precipitat ing drawing is intended merely to illustrate ing into the ash-pit 9,1 such ash as may acmore or less diagrammatically means for cumulate within the mass 12'. li lan-holes 22 95 carrying out the several operations hereinand 23 are provided for the purpose of before outlined. but it is to be understood cleaning out the decomposition chambers that the invention is not limited to the emwhen desired. Since most of the ash ac ployment of any specific type of apparatus cumulates adjacent the nozzle the gate in for many modifications may be resorted to further serves to support the n'iass oi" the 100 without departure from the invention. proof untterial in upper combustion chainln the accompa ying drawing her 17 so that the mass in lower (-liainlr-n' in Figure 1 a sectional perspective riew of" may be removed and. washed or otherwise one of the main generators and cleansed without the necessity of taking out Figure 2 is a side elevation of a battery all of the mass. 105

showing two of said main generators and In operation only one of the mam gena centrally arranged receiver generator. erators is used at a time, that is while one Like numerals designate corresponding is being used to generate gas the other is parts in both of the figures of the drawiaving its mass 12 heated by the burner in a l0 and vice 'versa, and, when the burner 10 110 tet'errin to the drawing and particw is in operation the generator with which it larly to Figure 2, it will be seen that a is associated iscut off from communication with the receiver generator 6 by means of valve 8 and When the burner is in operation Valve 9 of stack 9 is opened to provide the necessary escape for the products of 00311- bustion. In construction the receiver generator is substantially like the main gea erator 5 except that it has no intermediate grate 16 but is entirely filled with a fire resisting mass 12. Since highly heated gas from one or the other oi the generators 5 is constantly passing through the receiver generator 6 it follows that the mass 12 therein is maintained in a heated state. A discharge pipe 24- leads from thereceiver generator 6 to any desired point but preferably through devices arranged to'absorb the heat and utilize the same; In the production of the most eilicient results it is desirable that the Water and coal dust be combined in predetermined proportions, these proportions being determined by the carbon content of the coal rather than by its volume.

It is, therefore, to be understood that the mixture delivered through the nozzl is in predetermined proportions, prei'er iv in the proportions of 149.79 lbs. of water to 100 lbs. of carbon content'o'l the coal' The coal is in a finely divided or powdered (3OYidition and consequently mixes unitorrnlv with the water so that the action of all parts of the spray is uniform. I have IfOlllNl that by con'ibining the hydro-carbon with the water in the proportions stated all of the water will be decomposed and consequently a minimum of residual. is the result.

Having described my inventioin what I claim is:

A gas generating apparatus comprising a pair of main generators, a mass of lire rcsisting material in each of said generatorm a heating element ilor said mass in each of said main gz enerators, a receiver generator, means for establishing or cutting oil cone munication between either of said inain geir erators and said receiver generator at will and a lire resisting porous mass within said receiver generator and in the path of the gases discharged by either of the main generators whereby the discharge oi hot gases from one main generator will maintain the porous material in the receiver generator in a highly heated condition while the other 11 ain generator is being charged.

In testimony whereof I aflix my signature.
